Damp-wiping cloth, sponge or the like and method for its manufacture

Abstract

A damp-wiping cloth (e.g., a sponge or the like) from a foam body of flexible foam material, the foam body ( 2 ) being interspersed with foam strips ( 3 ) whose hardness is greater than the hardness of the foam body ( 2 ).

1. A damp-wiping cloth comprising a sponge body of flexible foam material, wherein the foam body ( 2 ) is interspersed with foam strips ( 3 ) whose hardness is greater than the hardness of the foam body ( 2 ), at least a portion of the foam body ( 2 ) lying between two of the foam strips ( 3 ), and
 wherein the foam strips ( 3 ) project with their lower edges or upper edges ( 5 ) from the foam body ( 2 ) of flexible foam material. 
 
   
   
     2. The damp-wiping cloth according to  claim 1 , wherein the foam strips ( 3 ) are produced by heat-sealing zones of the flexible foam material. 
   
   
     3. The damp-wiping cloth according to  claim 1 , wherein the foam strips ( 3 ) are made of individual harder foam parts from rigid foam material. 
   
   
     4. The damp-wiping cloth according to  claim 1 , wherein the foam strips ( 3 ) are diagonally arranged in the foam body ( 2 ). 
   
   
     5. The damp-wiping cloth according to  claim 1 , wherein the foam body ( 2 ) is provided at least on one of its surfaces with an abrasion-proof layer ( 23 ,  24 ) of abrasive non-woven material, abrasive coating, PU-foam (rigid foam) or another cloth material. 
   
   
     6. The damp-wiping cloth according to  claim 1 , wherein the flexible foam material is made of polyurethane, cellulose, regenerated allulose, lyocell or blends thereof. 
   
   
     7. The damp-wiping cloth according to  claim 1 , wherein the harder foam strips are made of polyolefins, polyurethanes or their blends. 
   
   
     8. The damp-wiping cloth according to  claim 1 , wherein the foam strips ( 3 ) have larger pores than the foam body ( 2 ) of flexible foam material. 
   
   
     9. The damp-wiping cloth according to  claim 1 , wherein the cloth is a sponge. 
   
   
     10. The damp wiping cloth of  claim 1 , further comprising a wringing mechanism configured to squeeze the sponge body. 
   
   
     11. The damp wiping cloth of  claim 1 , further comprising a holding device configured to hold the foam body ( 2 ). 
   
   
     12. A damp-wiping cloth comprising a sponge body of flexible foam material and a wringing mechanism configured to squeeze the sponge body,
 wherein the foam body ( 2 ) is interspersed with foam strips ( 3 ) whose hardness is greater than the hardness of the foam body ( 2 ), 
 wherein the foam strips ( 3 ) are diagonally arranged across a width of the foam body ( 2 ), 
 wherein the foam strips ( 3 ) extend from a first surface of the foam body ( 2 ) to an opposing surface of the foam body ( 2 ) along a height of the foam body ( 2 ), and 
 wherein the wringing mechanism squeezes the foam body ( 2 ) by moving at least one of the first surface and the second surface relative to the other of the first surface and second surface. 
 
   
   
     13. The damp-wiping cloth according to  claim 12 , wherein the foam strips ( 3 ) project with their lower edges or upper edges ( 5 ) from the foam body ( 2 ) of flexible foam material. 
   
   
     14. The damp-wiping cloth according to  claim 12 , wherein the foam body ( 2 ) is provided at least on one of its surfaces with an abrasion-proof layer ( 23 ,  24 ) of abrasive non-woven material, abrasive coating, PU-foam (rigid foam) or another cloth material. 
   
   
     15. The damp-wiping cloth of  claim 12 , further comprising a holding device configured to hold the sponge body. 
   
   
     16. The damp wiping cloth of  claim 12 , wherein the foam strips ( 3 ) have larger pores than the foam body ( 2 ) of flexible foam material.
